4.2.4
Each PORTA pin is multiplexed with other functions.
The pins and their combined functions are briefly
described here. For specific information about individ-
ual functions such as the comparator or the A/D, refer
to the appropriate section in this data sheet.
4.2.4.1
Figure • shows the diagram for this pin. The RA0 pin is
configurable to function as one of the following:
• a general purpose I/O
• an analog input for the A/D
• an analog input to the comparator
• an analog input to the Ultra Low-Power Wake-up
• In-Circuit Serial Programming™ data
4.2.4.2
Figure • shows the diagram for this pin. The RA1 pin is
configurable to function as one of the following:
• a general purpose I/O
• an analog input for the A/D
• an analog input to the comparator
• a voltage reference input for the A/D
• In-Circuit Serial Programming clock
